FIELD EVALUATION OF SKID RESISTANT SURFACES

THIS PROJECT WAS UNDERTAKEN TO ESTABLISH A THIN BITUMINOUS SURFACE COURSE THAT WOULD POSSESS GOOD SKID RESISTANT QUALITIES AND BE BOTH ECONOMICAL & DURABLE. ELEVEN DUPLICATE 1000 FOOT TEST SECTIONS WERE CONSTRUCTED ON A ROADWAY THAT CARRIED APPROXIMATELY 9700 VEHICLES PER DAY. THESE TEST SECTIONS CONTAINED FOUR DIFFERENT TYPES OF BITUMINOUS MIXTURES. (ASPHALTIC CONCRETE, SAND ASPHALT, PLANT MIX SEALS, AND SLURRY SEAL), AND THE AGGREGATES USED CONSISTED OF CRUSHED GRAVEL, SLAG, EXPANDED CLAY, AND GRANITE. THE EVALUATION OF THE TEST SECTIONS WAS BASED PRIMARILY ON THE SKID-RESISTANT QUALITIES OF THE MIXTURES, WITH CONSIDERATION GIVEN TO THE EASE OF CONSTRUCTION AND FINISHED RIDING SURFACE. SKID RESISTANCE WAS OBTAINED ON EACH OF THE TEST SECTIONS AT APPROXIMATELY FOUR-MONTH INTERVALS TO ELEVEN MONTHS AFTER COMPLETION. AT ELEVEN MONTHS, THE FINAL RESULTS WERE OBTAINED ON THE TEST SECTIONS, WHICH HAD CARRIED A TOTAL OF 3,209,346 VEHICLES. THE EVALUATION INCLUDED COMPARISONS OF SKID NUMBERS AND ROUGHNESS RESULTS AT DIFFERENT TIME INTERVALS AFTER COMPLETION. IN GENERAL, THE PLANT MIX SEALS PROVED TO BE THE MOST FAVORABLE OF THE DIFFERENT MIXTURES. THE SLAG AND EXPANDED CLAY PLANT MIX SEALS GAVE HIGHER SKID NUMBERS THAN CRUSHED GRAVEL. THE EXPANDED CLAY, SLURRY SEAL, AND KENTUCKY SAND ASPHALT ALSO RESULTED IN HIGH SKID NUMBERS. AFTER ELEVEN MONTHS OF TRAFFIC, THE EXPANDED CLAY HOT MIX SHOWED THE HIGHEST SKID NUMBER. THE PLANT MIX SEALS GAVE THE LOWEST ROUGHNESS READINGS UP TO ELEVEN MONTHS AFTER CONSTRUCTION, WHILE THE KENTUCKY SAND AND SLURRY SEALS GAVE THE HIGHEST. /AUTHOR/
